I'm trying everything I put styrofoam in and notched it out so it sits down in it. I run it for a bit but still seams noisy like the impeller hitting something and lots of vibration. I have to wait to pump more water rodi making more. I have the mag 18 under sump and it's quiet I could swap pumps around but I'm not sure if I will have enough flow. 7C825FBBA03A_zpsw5sye0eg.jpg[/IMG]
I even insulated line out of pump and under header system connected to pump so nothing vibrates on glass
